    Abstract
    Contents enhancement of catalog records may increase access to books in collections and aid in effective resource sharing by providing more detailed descriptions about library holdings in the catalog. A sample of monographs in San Diego State Univ. Library was studied to determine the extent to which information in books from parts of the collection could be represented better by content notes, and to determine how much of this information has subject or analytical applications. The study revealed that approximately 23% of the books contain discrete content information not already represented in catalog records that could be added. Of those, 52% would be citation-based enhancements and 48% would be subject-based. Nearly 65% would require fewer than 25 enhancements, with an average of 8.03 enhancements per book for the total population

    Abstract
    Indexing terms supplied by authors can increase subject control of their documents. The terms can be used in the creation of indexes, abstracts, and other devices for information retrieval in the special library. An examination of the American Mathematical Society author indexing program suggests that contributions of authors enhance indexing efforts of editors

    Abstract
    Analysis of research to date on improving subject access by including contents tables in bibliographic records. Results indicate the need for clear methodology (criteria for selecting notoces for enrichment, manual and semi automated methods, cost). Evaluations, based on recall, precision and rate of circulation, indicate manifest benefits, especially in virtual libraries where information is superabundant; but enrichment is a complex process

    Abstract
    Contents notes can improve online access to works containing essays, short stories, and significantly titles chapters. Few records in bibliographic utilities include contents notes. The OCLC PRISM service may provide an opportunity to cooperatively build a contents-enriched database. This paper discusses some issues related to the creation of enhanced records and their display in online cataloges. It also describes one library's efforts to add contents notes lically and to participate in an anticipated OCLC pilot project

    Abstract
    This article describes our efforts in supporting information retrieval from OCR degraded text. In particular, we report our approach to an automatic cataloging and searching contest for books in multiple languages. In this contest, 500 books in English, German, French, and Italian published during the 1770s to 1970s are scanned into images and OCRed to digital text. The goal is to use only automatic ways to extract information for sophisticated searching. We adopted the vector space retrieval model, an n-gram indexing method, and a special weighting scheme to tackle this problem. Although the performance by this approach is slightly inferior to the best approach, which is mainly based on regular expression match, one advantage of our approach is that it is less language dependent and less layout sensitive, thus is readily applicable to other languages and document collections. Problems of OCR text retrieval for some Asian languages are also discussed in this article, and solutions are suggested

    Abstract
    Describes an approach to indexing which seeks to eliminate the shortcoming of the representation of information in existing bibliographic catalogues: Subject Access Project (SAP) indexing which has been used successfully at Lund University and elsewhere. Existing catalogue records have been enriched with terms selected from lists of contents and indexes in books thus facilitating access to specific parts of documents and smaller semantic entites such as chapter titles, subject titles and data in graphic or tabulated form available in a wide range of publications

    Abstract
    Bibliotheken sind nicht chaotische Sammlungen von Medien, sondern werden stets als Information-Retrieval-Systeme implementiert, denn das Wiederfinden bei exakten und vor allem bei vagen Anfragen ist von Anfang an das Sammlungsziel. Niemand kennt zum Zeitpunkt der Sammlung die Fragestellung, die einen zukünftigen Benutzer zu diesem Medium führen wird. Die Art der Sammlungsorganisation bestimmt in hohem Maße die zukünftig mögliche Antwortmenge und deren informatorische Qualität. Der Siegeszug der digitalen Information-Retrieval-Systeme im Internet hat in den letzten zehn Jahren Erwartungen und Märkte geschaffen, die weder Karteikarten, noch deren digitales Ebenbild, die heutigen Bibliotheksmanagement-Systeme befriedigen können. Es genügt nicht mehr, dass Google und andere kostenlos das aufsammeln und nachweisen, was im Internet frei zugänglich ist. Alte, noch »marktfähige« Inhalte werden neu aufbereitet, mit neuen Inhalten kombiniert, um neue Geschäftsfelder zu schaffen. Es geht um Verdrängung und Neuverteilung, und die älteren Inhalte der Bibliotheken sind meist noch hinreichend »marktfähig«.

    Abstract
    The author collected information about tables of content and index terms in 125 books borrowed by patrons in a medium-sized academic library. To learn how useful the term would be as subject terms in a library catalog, he determined which of these terms were the same as the words used by the patrons to describe the books. For 72,4% of the books assigned LCSH, the patron's term matched the LCheading. The patron's term matched the table of contents term for (1,3% of the books with tables of contents. If the catalog had included terms from the tables of contents and the indexes in addition to the LCSH, the success rate would have been 97,3%. One problem in using terms from books in a library catalog is that many books lack indexes and/or tables of context

    Abstract
    Describes the Intelligent Literature Search Assistant (ILSA) which demonstrates the possibilities of a fully automated cataloguing workbench in an object orientated environment. Although developed with OPAC users in mind, it can be very useful to cataloguers in aiding both classification and subject heading access. Also describes work done at the University of Strathclyde in the area of machine learning and knowledge based systems, the Structured Information Management: Processing and Retrieval project (SIMPR). Advocates the use of uncontrolled vocabulary headings in conjunction with systems like ILSA, a layered approach rather than direct first point access, in order to make subject cataloguing easier and more relevant and the subject catalogue more useful to others

    Abstract
    The paper examines the developmentss that have taken place during the last decade with respect to the provision of intellectual subject access in information databases storage. The principles of the SAP indexing methodology are outlined and exemplified, leading to a discussion of the consequences for the conception of the physical 'document' versus 'semantic entities' as the basic constructs for storage and multi-dimensional representation of subject matter. Finally, the paper analyzes the impact of very recent technologies which make achievable such access conceptions and mechanisms

    Abstract
    Subject access plays an important part when plans are made for an on-line public access catalogue (OPAC). Therefore, current subject searching facilities in OPACs should be accessed carefully. These facilities include, amongst other things, phrase searching, keyword searching and class number retrieval. Users reaction have been instrumental in identifying certain shortcomings in subject access to OPACs. Points out certain shortcomings in subject access, as shown by a number of research projects undertaken during the past decade. Highlights aspects which could, in future, improve subject access in OPACs. This could be achieved by either enhancing content representation in the records within the OPAC data base or by enhancing the searchability and browsability of the OPAC. Considers whether the on-line catalogue will ever be a finished, perfect product, or achieve the universal, familiar uniformity experienced by users of the 20th century card catalogue.

    Abstract
    This paper analyzes proposals for augmenting library bibliographic records for improved subject searching in online catalogs. Possible fields for enrichment are described and their likely value assessed. The assessment determines that the main value of enriched records would be to provide access to parts of books. The paper presents arguments for and against adding book content indexing to the online catalog and analyzes the feasibility of eleven alternatives for providing such information

    Abstract
    As librarians plan ahead to make subject enhancements available to online searchers in various possible file locations and formats, they may want to base their decisions on implications for online searching. This paper explores some of these implications with respect to unique and misleading terminology in tables of contents, Choice abstracts, and reviews from Computing reviews for thirty-six books on information and computer science chosen from the 1987 issues of Choice. It also discusses possible interacting functions in the search process served by these subject enhancements, assigned LCSH, and book title terminology

    Abstract
    Experimental evidence suggests that enhancing the subject content of OPAC records can improve retrieval performance. This is based on the use of natural language index terms derived from the table of contents and back-of-the-book index of documents. The research reported here investigates the alternative approach of translating these natural language terms into controlled vocabulary. Subject queries were collected by interview at the catalogue, and indexing of the queries demonstrated the impressive ability of PRECIS, and to a lesser extent LCSH, to represent users' information needs. DDC performed poorly in this respect. The assumption was made that an index language adequately specific to represent users' queries should be adequate to represent document contents. Searches were carried out on three test databases, and both natural language and PRECIS enhancement of MARC records increased the number of relevant documents found, with PRECIS showing the better performance. However, with weak stemming the advantage of PRECIS was lost. Consideration must also be given to the potential advantages of controlled vocabulary, over and above basic retrieval performance measures

    Leseprobe: "Bibliothek sind Information Retrieval Systeme Bibliotheken sind nicht chaotische Sammlungen von Medien, sondern sie werden stets als Information Retrieval Systeme implementiert, denn das Wiederfinden bei exakten und bei vagen Anfragen ist von Anfang an das Sammlungsziel. Niemand kennt zum Zeitpunkt der Sammlung die Fragestellung, welche einen zukünftigen Benutzerzu diesem Medium führen soll. Die Art der Sammlungsorganisation bestimmt in hohem Maße die zukünftig mögliche Antwortmenge und deren informatorische Qualität. Viele Sammler kennen die einzelnen Medien recht gut durch eigene Lektüre oder Nutzung, durch Verarbeitung der Inhalte in eigenen Schriften, durch Kenntnis der Autoren oder durch Einschätzungen, Empfehlungen, Meinungen von anderen. Diese Sammler sind "Antwortmaschinen" - können oft mit hoher Präzision und angepasst auf den Kenntnisstand des Fragenden Erklärungen geben, welche aus einer Summe von Medieninhalten gelernt wurden. Genau diesen Typ wünschen sich die meisten Benutzer, führt er doch schnell, fachlich ausgewogen und verständlich ans Ziel. Der nicht ganz so begabte Sammler oder Sammler deutlich größerer Medienmengen kann nur mehr oder weniger gut, auf einzelne Medien oder Mediengruppen hinführen, gibt aber keine fachliche Auskunft mehr - sondern liefert nur Hinweise auf mögliche "Antwort-Container". Zumindest seit der berühmten Bibliothek von Alexandria hilft dieser Sammler seinem eigenen Gedächtnis mit kurzen Notizen nach: Listen von Titeln, von Autoren, von Themen und Referenzen auf den Standort. Praktischer als geschriebene Listen sind wegen der leichteren Sortierbarkeit Karteikarten. Der digitale Record in den Datenbanksystemen der Bibliotheken ist logisch nichts anderes, nur deutlich schneller sortierbar. Als sich in den Siebziger Jahren die heutigen Bibliothekssysteme entwickelten, entschieden sich fast alle Anbieter für zumeist relationale Datenbank-Management-Systeme als Basis-Technologie - gut bewährt in Lagerverwaltung und Buchhaltung in Wirtschaft und Verwaltung. In Welten mit sehr wenig Textinformation. Vage Suche war im Ansatz nicht vorgesehen, ging es doch zunächst nur um digitale "Karteikarten".
    Information Retrieval, Digitalisierung, Speichersysteme, Virtualisierung und Weiterentwicklungen der Datenbank-Management-Systeme erlauben heute aber, dass Katalog und Medium technisch zusammenfallen und eine ganz neue Qualität erreichen können. Kataloganreicherung, wie seit 2002 von der Gruppe um dandelon.com betrieben - angefangen hat es in Bibliotheken in Vorarlberg, Liechtenstein und Schweiz, heute zählt Deutschland, Norwegen, Schweden und Italien dazu - versucht Information Retrieval-Technologie mit den relationalen Datenbanksystemen der Bibliotheken zusammen zubringen. Dazu werden mehr Daten benötigt, als die bisherigen bibliothekarischen Titelbeschreibungen hergeben. Sprachverarbeitungskonzepte sind notwendig, um die Vielfalt der Sprache wieder einzufangen und neue Konzepte für die Anzeige die-serTexte oder anderen Datentypen. Kataloganreicherung ist die derzeit technisch sinnvolle Voraussetzung zum Einsatz von moderner Information Retrieval-Technologien in Bibliotheken. Deren Einsatz ist bei Bibliotheksverbünden auf dem Vormarsch. Die maschinelle Indexierung - mit linguistischen und/oder statistischen Methoden - ist ein mögliches Verfahren in Information Retrieval-Systemen, dessen Resultate auch direkt in "klassischen" OPAC-Systemen nachgenutzt werden kann und damit auch dort eine Recherche auf breiterer terminologischer Basis gestattet. Diese Erweiterung des OPACs um die maschinellen Indexierungsergebnisse stand bei der Vorarlberger Landesbibliothek, dem Pionier unter den "Kataloganreichern" und wohl noch immer größten Einzel-Produzenten, schon 2002 vor der Anzeige der Inhaltsverzeichnisse im Vordergrund. Die maschinelle Indexierung aus intelligentCAPTURE kann leicht in die Kataloge übernommen werden. Schon bald zeigte sich aber im jeweiligen Bibliothekssystem das fehlende Ranking. 2004 startete deshalb "dandelon.com". Die maschinelle Indexierung wird in homöopathischer Dosis in den HEBIS-Katalog übernommen und kommt derzeit beim GBV. Für die Deutschen Nationalbibliothek hat Frau Direktor Dr. Niggemmann auf dem Deutschen Bibliothekartag 2009 in Erfurt die maschinelle Indexierung Klassifizierung, Extraktion weiterer Metadaten und die Ergänzung um zusätzliche Daten - auch abweichend von bisherigen Normdateien - als Projekt angekündigt und deren Übernahme in den Katalog. Ein Meilenstein! Die DNB kündigt damit den Perspektivenwechsel der bibliothekarischen Sicht hin zur Sicht des Endbenutzers an."
